Sprinkler

The automatic sprinkler fire extinguishing system is made up of a set of automatic extinguishers called sprinklers and the relative supply piping containing water, compressed air or ambient air (deluge systems) and control valves fed by water supply sources of suitable flow rate and autonomy. They also include a test device and an alarm bell. The sprinkler heads can be open (deluge systems) or closed, generally the closure is accomplished by a quartz bulb filled with a special liquid with a high dilation coefficient. When a fire breaks out in the area protected by this system, the rise in temperature causes the glass bulb to break and the water to be sprayed from the nozzle.

The System is therefore designed in such a way that, depending on the risk, the quantity of water that is distributed by the sprinkler heads that open is enough to extinguish or keep the fire under control.
